Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 3 km towards west.
According to the given information:
From the diagram;
ST = RS - (RT = QP)
ST = 6 - 3 = 3
ST = 6 - (6 - PQ)
ST = AB
AB = 3 km
Hence, he should travel 3 km towards the west from point B to reach point A.
